38. [3.] Cryptobium texanum, n. sp.—Castaneous, sparsely pu-

Bosque Co., Texas, Mr. G. W. Belfrage. Differs from C.

bescence fine. Head elongate, parallel behind the eyes, hind angles and

placed. Elytra densely less strongly punctured, less shining, not longer 
tnan the prothorax. Abdomen finely and densely punctured. Antenne 
and legs yellow testaceous. Eyes of the same sizé asin C. californicum,
